Grids in Tabs not rendering upon tab activation in IE6

I'm quite certain this was working fine previously with earlier builds... not sure exactly when it broke.

Still working fine in Firefox, but quirky in IE6.

For a layout region with multiple tabs, whereby each tab hosts a grid, and all grids are loaded at the same time (i.e. only one grid visible at any one time) - upon switching to another tab, the grid rows are empty.

The grid rows reappears upon either a container resize or simply moving the mouse cursor over any of the invisible grid records.

I just did a commit with the latest code. It has the display:none tabs workaround in place (and other stuff). See if that fixes it for you.

What it does is if the tab item panel has position relative it uses negative positioning instead of display none. This way offsets are still available and grids should render as expected. It may need a little tweaking.
